Executive orders are assigned numbers and published in the federal register, similar to laws passed by Congress, and typically direct members of the executive branch to follow a new policy or directive. Trump issued 32 orders.

Presidential memoranda do not have to be published or numbered (though they can be) and usually delegate tasks that Congress has already assigned the president to members of the executive branch. Trump issued 28 memoranda.

Finally, while some proclamations — like President Abraham Lincoln's Emancipation Proclamation — have carried enormous weight, most are ceremonial observances of federal holidays or awareness months. Trump issued 30 proclamations.

Scholars have typically used the number of executive orders per term to measure how much presidents have exercised their power. George Washington signed eight his entire time in office, according to the American Presidency Project, while FDR signed more than 3,700.

In his two terms, President Barack Obama issued 277 executive orders, a total number on par with his modern predecessors, but the lowest per year average (35) in 120 years. Trump signed 32 executive orders in 100 days.
